Hello All,

CSR5-----------------------CSR7
XRV9K1 is PCE and CSR3 is PCC.
'on-demand' policy is configured on CSR3. And affinity for the policy is 'include-any name GOLD'. According to my understanding policy should take any path which has GOLD affinity. Am I correct ?
Affinity of link between CSR5 and CSR7 is 'GOLD' colored but still CSR3's policy take path via CSR6. I do not know what config am I missing. Below is the complete configuration.
